There are many options to buy glasses online nowadays. Some of the most important differences between glasses purchased from online retailers and from a trained optician in-person include:

Accuracy of measurements
- Lenses need to be measured with the frame on your face for the best accuracy
- Lens measurements include much more than just a pupillary distance (PD)
Quality of lens treatments
Lens and frame adjustments can be made by an in-person optician
